4. Display the active zone set on each switch using the Zoning Active
command or the Active Zoneset tab of the SANsurfer Switch Manager
topology display. Compare the zone membership between the two active
zone sets. Are they the same?
 Yes - Contact your authorized maintenance provider.
 No - Deactivate one of the active zone sets or edit the conflicting zones
so that their membership is the same. Reset the port. If the condition
remains, contact your authorized maintenance provider.
5.1.2.2
Excessive Port Errors
The switch monitors a set of port errors and generates alarms based on
user-defined sample windows and thresholds. These port errors include the
following:
 CRC errors
 Decode errors
 ISL connection count
 Login errors
 Logout errors
 Loss-of-signal errors
Port threshold alarm monitoring is disabled by default. Refer to the
SANbox2-8c/16 Switch Management User’s Guide for information about
managing port threshold alarms.
If the count for any of these errors exceeds the rising trigger for three consecutive
sample windows, the switch generates an alarm and disables the affected port,
changing its operational state to “down”. Port errors can be caused by the
following:
 Triggers are too low or the sample window is too small
 Faulty Fibre Channel port cable
 Faulty SFP
 Faulty port
 Fault device or HBA
Note: This can be caused by merging two fabrics whose active
zone sets have two zones with the same name, but
different membership.
